New cryogenic ball valve from Flow-Tek

Flow-Tek, a subsidiary of Bray International, now offers cryogenic ball valves to be used in the production, transportation and storage of liquefied gases

Flow-Tek, a subsidiary of Bray International, now offers cryogenic ball valves to be used in the production, transportation and storage of liquefied gases.

These specially designed valves have extended stems and bonnets installed to position the stem packing above the cryogenic fluid and provide a column of warmer vapour that insulates the stem seal from the effects of low temperatures.

Flow-Tek has based the cryogenic valve on their reliable stainless steel Triad 3-piece valve available with various end connections including threaded, socket weld and butt weld.

These valves are also available in the Flow-Tek F15 flanged valve design.

Valves are available in sizes 0.5'' to 4''.

Some of the key features include high-density TFM-1600 seats and seals throughout the valve that enable the valve to be rated down to -425F service.

Each valve is permanently marked with a flow direction arrow to prevent incorrect installation.

Live loaded stem packing is utilised providing self-adjustment to compensate for wear and also thermal expansion and contraction.

All valves are provided with blow-out proof stems and all valves are cleaned before shipment to remove all grease and oils that may react with the service media.

Flow-Tek, headquartered in Houston, is a leader and innovator in process control automation, with worldwide manufacturing and distribution facilities.

Products include manual and automated 0.25'' through 12'' ball valves, pneumatic and electric actuators, valve status monitors, electro-pneumatic and pneumatic positioners, solenoid valves and control accessories.
